This invention relates to methods of and devices for treating threadcoils or similar airiular masses of spun filaments of artificial s1 ln the artificial silk industry it is known, for the purpose of further treating the spun filaments coiled to annular masses in the spinning can to remove the said iilaments from the can, to pressthem-ilat and to subsequently pack them into trays or similar containers with perforated walls before exposin them to the action of a liquid. Thereby t e employment of special supporting sleeves orthe like for the coils is rendered superfluous, but the latter when treated in this manner before being reeled require to be individually opened up' again by the aid of special widening means, so as to re-assume their original annular shape.

According to the invention the method of treating the annular masses of spun laments or similar coils .of artificial silk is distinguished by the annular masses of artificial silk threads after their removal from their supports being arranged in rows around a tensioning appliance having radially movable tensioning members, withthe latter in retracted position, under avoidance of any contacting with 'the said members, and thereupon being commonly expanded by the same members from inside to outside in the radial direction and consequently brought to bear thereon, whereater, with the tensioning appliance accommodated in upright position inside of a container, the annular masses of artiicial silkstacked on the said appliance are subjected to a liquid treatment in amanner known per se.

Thus the thread coil is adapted to be subjected in a manner to a liquid treatment which renders the treatment simple and thoroughly performable inv a short time, whereby the annular sha e of the thread coil is maintained thus permitting the thread to be reeled after the wet treatment without any further provisions.

ln `the accompanyindrawing several constructional forms of a evice for carrying the method into effect are illustrated by-way of example only, wherein 471,880, and in Germany August 9, 1929.k

Fig. 1 shows a section of a first constructional form of the device with thread coils stacked to form a column;

Fig. 2 is a section on the line II-l of Fig. l;

Fi 8 is a top plan view of the separating mem er.

rlhe present method enables the annular in ass of'spun filaments obtained in the spinning can as well as the coils produced on the spinning spool in the parallel spinning process to be further treated in the same manner. The annular mass obtained in the spinning can is readily removable from the can and the coil produced on the spool is easily slid o the latter when the spool is constructed for changing its diameter.

Then the coil 3 for the further treatment, such as Washing, de-sulphurizing, bleaching, drying or eventually dyeing and the like respectively is slid on a hollow core or a standard 2 placed in a container l (Fig. 1) which for certain purposes is closed. The standard 2 is provided with outwardly movable parts each consisting of a pair of parallel exterior and interior longitudinal bars 4 and 4 interconnected by two transverse bars 4 so as to rovide a complete frame. In Fi 2 these rames are'shown six in number w ich by the bars 4 bein slidably'arran ed in the mantle of the stan ard 2 are simu taneously moved radially outwardly with the bars 4 extending parallel to the axis of the standard when the plug 5 is inserted between the bars 4c. After the coil 3 is mounted to the standard 2 or preferably a plurality of. coils in superposeo position, the outwardly movable parts are ex ended, thus securing the coils B thereon. T is may be accomplished'before the standard is'inso as to form a column,

vsa

a serted in the container 1 with its lower end iittin in a socket 6 in the bottom of the latter. e coils 3 bearing tightly on each other, without leaving any interstces between them or between the lowest `coil-and the bottom of the container; provide a sealed vessel with the said bottom when they are covered at the top by a cover 6 associated withl each standard 2. The lower end of the standard joins with a conduit 7 ending in the socket 6', all of the conduits 7 being connected at their other end with a' suction or pressure main 92 connected to a suction or pressure pump 9 res ctively,` de nding on the direction in which the liqui si 22 and gases required for the further treatment of thefsilk are to be passed through the coils 3. For this purpose the standard 2 is apertured such as at 2. to allow the treatment medium to pass from the interior of the container 1 through the windings of the coils 3 into the hollow space 5 between the coils and the standard 2 and from there through the apertures 2 .into the pump 9 via the conduits 7 and 9 in the direction of the arrows in Fig. 1 or `rice versa.

In this manner a quick end thorough treatment of the coils is ensured the treatment medium nding no other wey in or out ei the tightl;r sealed colunm provided by the coils then through the individuel windings of the imiter in uniio-rm distribution. Upon choice the treatment medium mey be caused to circulate through the described psth repeatedly when the other end the pump El is connested with the container l by e return ceuduit.

The described method lies the advantage that for the further treatment of the goods any spools or the like 'se supports fer the coils 3 een be dispensed. with, whereby greet economies ere obtained. Furthermore, the advantage crises that 'the new method is equally spplicshle to coiis obtained in the inning can or on speels 'ti-'ie parallel spinning method.

The device she-Wn in Fig., l is based on the 'seme principle as that iilustreted in l, the dierence between the 'two devices re-l siding in their construction. instead of u. standard skeleton core is provided.

The base 10 of the skeleton core is formed Y with recesses 12 arranged in a. regular cctagon around the central bore le of the base, A for thev lower ends of the har-shaped longimounted on s plete 2e tudinal members 13 to enter so as toY be loose-w ly accommodated therein. It is obvious that instead of an Octagon any other regular polygon, for instance, a hexagon may be used.

15 designates an elastic connecting member,

'of the wall of the respective recess and to hold them together in this fashion and at the same time to secure them against dropping out of the base, thus forming a selfcontained unit together with the latter (Fig. 5). A headpece 16 is provided with a conical ortion 17 for entering between the longitu inal bars 13 of the skeleton core and to press them apart when the head piece is placed on top of the core. v

fig. 8 shows a flat separating member 18. having a central opening 18 which follows the contour of the longitudinal bars when Isssembled in the base 10. The free ends oi the thus formed ears 20 between the notches 19 for the longitudinal bars 13 are bent up for axially centering the thread coil or annular mass of spun filaments 21 respectively which they support (Fi '2). The separating members 18 s'uitabiy consist of a nie-.termi which is indiierent to the liquid to be used for the "il ther treatment 'of the thread coils. A hoiiow coter or ccp 23 serves for covering the tcp-most thread coil 2l f el) of o plurality of coils piled up around the skeleton core orrn e Column -i'ter the heed piece 16 hes inserted wee longitudinal bers 13 of the skelethus f the bers to from :7 l thread coils. 1 @or 1 c inveution as s s 2l in the above-described manner are which is inserteble in e container' or tub 9.5 (Fig. 4). ln the double bottom 26 of the tub openings 2'? with superpesed sealing members 28 are a.rs.nged. ln the inserted position of the 'asse plate 2li in the tuo openings 27 register with the bores 29 in. 'the base plate, o es te enable the liquid 22 to flow oi from tub between the double hot-toro. 26,

of the aroi" imiter in the direction rews.

For this purpose, as descri in connecwith. the previous constructional forms of the device an under-pressure is caused between the deuble bottom of the tub, or when the letter is ciosed on top., pressure may be applied 'to the interior of the tub, wherester the treatment liquid 22 is forced through the windings of the Avarious thread coils to perierm the wet treatment.

arelitj o1' column sssembied of thread' llli In course of this -treatment the threadcoils ordinarily shrink, v thus causing the height of the column to decrease. The cover 23 is so shaped, as to take care of this shrinkag and to permit the coils to always bear tig tly on each other, thus leaving no other exit for the liquid than through the windings of the coils. a
